PLANER i ATTACHMENT.

Application filed July 1, 1918. Serial No. 242,754.

in the art to which it appertains to make. and use the same, reference being had tothe. accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to attachments for planers by, means of whichv the planer may be adapted to perform circular work as well as fiat work, and the object is to perform such circular work without having to resort to a lathe and to save the expense of a lathe.

Briefly the invention comprises principally a live stock mounted on the usual overhanging tool-carrying frame, and connections for imparting rotation thereto about a vertical axis. This stock is adapted to engage the top of a piece of work and to rotate the same. The lower surface of the work is spaced slightly from the planer bed and is rotata-bly mounted upon a dead stock composed of a single pin in a perforation in the planer bed and in vertical alinement with the axis of the live stock.

The attachment is designed for stone working but is not limited thereto.

Referring to the drawings forming a part of this specification:

Figure l is a side elevation of a planer with my attachment mounted thereon.

Fig. 2 is a front, elevation on a larger scale than Fig. 1 taken on line 2-2 of Fig. 1 showing a fragment of the planer with the attachment applied thereto and a block of stone A in operative position in section.

Fig. 3 is a planof the live stock indicated by line 3-3 of Fig. 2.

. Fig. 4 is a side elevation of the attachment as indicated, by line M of. Fig. 2 and show-s the manner of mounting the same on the overhanging frame.

Fig. 5 is a vertical section on line 55 of Fig. 4.

4 Fig. 6 is chiefly a plan as indicated by line 66 of Fig. 2. p

The ordinary reciprocating planer bed 12 mounted on base 13- is shown with an upright stand-ard- 14, having an overhangingframe 15. This frame ordinarily carries a tool-stock, which may be retained if the topof the stone is tobe operated upon while the present invention i-sbeing used, or may be removed otherwise.

The height of this frame may be varied by means of anwadjusting screw- 1 6; oper able in the standard 14- byany suitable means (not shown); On the lower part ofthe standard; 14. a tool-stock, 17' may behingedly -mounted as at '19- and-carry--a tool 18.

The attaclnnent" is composedof two journal blocks20 and 21 slidably mounted on framel5. The lower partsof the'se blocks are dovetailed on the frame 15 at 22 while the upper part of each block is secured to a flange 115 of the frame by an overhanging plate 23 secured to the block by screws 24. Shims 25 are placed between plates 23 and flange 115 for properly positioning the blocks and taking up wear and are held in position by set screws 26.

The block 21 is provided with two lateral journals 27 in which a vertical shaft 30 is mounted. The upper end of this shaft is provided with a bevel gear 31. The upper parts of the block 21 and block 20 are pro vided with upper journals 28 and 29 respectively in which a horizontal shaft 33 is mounted. The inner end of this shaft is provided with a bevel gear 32 in mesh with bevel gear 31. Shaft 33 is provided also v with keyways 34, a loose pulley 35 retained on the shaft by sleeve 36, and a fixed pulley 37 keyed to the shaft as shown. These pulleys are driven by belt 38 connected with motor 39 mounted above on standard 14. A

belt shifter 50 may be used.

A The lower end of shaft 30 is fitted with a live stock 40 having a center pin 41 and driving lugs 42 adjustably mounted in slots 43. This live stock engages the upper surface of the block A for rotation thereof and cooperates with a dead stock 45 composed of a pin seated in one of the perforations 46 in the planer bed and arranged in vertical alinement with the'axis of the live stock.

' Thus it will be seen that power delivered by the belt 38 is transmitted to the vertical shaft 30 and through live stock 40 to the block A whose under face is mounted to rotate on pin 45. It is understood, of course,

that the table 12 is anchored against movement while the above operation is being performed.

When the block is set in motion the tool 18 may be manipulated in the usual manner.

It will be seen, therefore, that by this simple attachment for a planer a lathe may be dispensed with entirely.

What I claim is:

1. The combination with a planer having a bed and an overhanging frame, of a vertical shaft mounted on said frame, and means on its lower end to impart rotary motion to a body to be operated upon.

2. The combination with a planer having a bed and an overhanging frame, of a vertical shaft adjustably mounted on said frame, means to drive said shaft and a live stock on the lower end of said shaft to impart rotary motion to a body to be operated upon and means to rotatably support the body.

3. The combination with a planer having a bed and an overhanging frame, of a vertical power driven shaft adjustably mountnaeaaaa ed on said frame, a live stock on the lower end of said shaft and a dead stock on the planer bed in alinement with said shaft, said stocks being adapted to support between them and impart rotary movement to a body to be operated upon.

4. The combination with a planer having a bed and an overhanging vertically adjustable frame, of a journal block adjustably mounted on said frame, a vertical power driven shaft mounted in said block, a live stock on the lower end of the shaft, and means on the planer bed in alinement with said shaft and upon which a block to be operated upon is adapted to rotate.

5. The combination with a planer having a bed and an overhanging frame, of a vertical shaft mounted on said frame, means on the lower end of the shaft to impart rotary motion to a block to be operated upon, and a dead stock on the planer bed in alinement with said shaft to support the block.

In testimony whereof I affix my signature.
